  • Copper electromagnets. Making them stronger.

    There are magnetic particles inside the iron. In soft iron, these particles will line up with an external magnetic field. In this way, the soft iron core behaves like a magnet itself. Once the external field is taken away, the core will return to normal. Imagine we put a piece of soft iron in the middle of a coil of copper
